Billed as “The Greenest Commercial Building in the World,” the grand opening of this six-story 50,000-sq-ft NZEB was held on Earth Day, April 22, 2013. The building is designed to have an energy use intensity (EUI) of 16 kBtu/sq ft/yr with all energy generation needs supplied by the rooftop solar array.

Melink Headquarters, Milford, Ohio. Designed as net-zero energy capable building and constructed in 2006, renewable energy systems were incrementally added until this 20,000-sq-ft building achieved net-zero energy status in 2011 with an EUI of 18.8 kBtu/sq ft/yr.

NREL Research Support Facility, Golden, Colo. This 360,000-sq-ft net-zero energy office building showcases numerous high-performance design features, many of which are a direct result of NREL research efforts. The building has an EUI of 35 kBtu/sq ft/yr, which includes a high-performance data center.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
